I have been a long time "lurker" on here, but just recently bit the bullet and started my owner build. I connected with a company that specializes in assisting owner builders and they drew up the plans and did the engineering. They also get bids from subs and have them sent to you, and then you negotiate with the subs. So far this process has been simple. I am posting some photos of the progress so far. Feel free to chime in with any hints, suggestions or ideas you have.
